Reply To: New coils no spark 1956 15 hp evinrude

Something odd about that much of a difference in resistance. Time to measure the coil itself connecting directly to the hi voltage (secondary terminal. ) and mag plate. You may have bad spark plug wire and or terminal rusted. If I may ask what resistance scale did you have your meter set on? The meter should say ohms, then times 10, 100, 1000 & so on to meg ohms. I have no idea why with new coils would show that much of a difference in resistance other than bad wires or connectors. What kind of spark plug wire was used? Must be copper wire, solid or stranded Yes when you show no resistance on the mag to block that is a great reading.
Check everything like the factory wire terminal where the connector is crimped on the wire. Electrical is like a chain, one bad link causes an open connection & system will fail. I in the past have always soldered the connector to the wire. Just added insurance it will not fail in a humid place.
Please pay attention to details & keep the magneto super clean. Everything will conduct electrical even air. As in lightening. Wish you were in Phoenix Arizona, I would help you in person,
Anyone have anything to add to my suggestions?
